It might seem like free flowing but I had that happen in a couple prints when I first got the M200 and when i put the bearings o it was amazing. Just cause you can turn it doesn't mean the little stepper motor can turn it that easy. But then it is only a thought. lol
I even had a print go bad the other day because my power cable was loose. It still printed but was messed up. I noticed the power cable loose but the machine never lost power. Pushed it in tight and the bad print was gone.
I would check all the wires and make sure they are seated and tight and that the ribbon cable is set.
I would also suggest printing some bearings. They really do work. I wouldn't believe it unless I saw it myself and I did. lol
now i have see, that the hobbed bolt has no securing screw on it! does any one know if this right or do they forgot to put a screw on it? ( see photo )
what is the distance from the front of stepper shaft to the front of the pully? so i can fix it my self with a securingscrew.
than i have take a closer look to the hole printer and i have found this issue, see attached video (its zipped, because .mp4 are not allowed to upload ).
every of the 4 screw are loose....
ohoh its weekend, its raining and i have a new printer whicht ist defective.... bad bad ;-)
I had the same problem with my (now) 1 week old printer. Filament could block itself and then the motor could scratch into the blocked part, making little pieces of plastic everywhere... if you add this to the wrapping problem, I let you to imagine... <_<
I fixed by cleaning all the plastic path: I cleaned the motor like you did, I also cleaned the path:
there was little pieces of (burnt) paper, burnt plastic and other dusts. Do have a look inside to verify it is all clean and empty of anything
Now, after each print, (photo 1)
I heat the extruder (photo 2)
I remove the nozzle (photo 3). Yes, I must wear gloves !
I wait it to be cold and I put it in Acetone for 4h30 (photo 4)
Then it is clean and I can remount everything (photo 5)
I now do the same after each print (yes, it is long, long, long :blink: but I think about buying a new hotend to swap them, one cleaning and the other one printing)

Why would you do this after Each print? Once in a while should be sufficient.
I hadn't cleaned the inside of mine since.....I can't remember and I use the M200 a lot. After all I am a printing company. lol
I understood the ball screw securing screws were intentionally left loose, because ball screw nuts require very careful alignment. If that is the case and you secure it, it will wear and also cause motion problems. Leaving them slightly loose allows it to self-align.
